= Evaluation of ORCHIDEE for N coumpounds emissions =

Working group

Mohamed Saad, Nicolas Vuichard, Juliette Lathiere, Didier Hauglustaine

Planned work

1-Perform a set of simulations with the ORCHIDEE model to quantify the fluxes of nitrogen compounds (NH3,NOx,N2O) emitted by the soil.

2-Evaluate simulated emissions at national, continental and global scales by comparing them to emissions by other methods such as inventories (eg: EDGAR).

3-Develop the coupling between ORCHIDEE and INCA models in terms of downward (deposition)and upward(emissions) N fluxes.

Team meeting: 06/03/2019

Define the work steps:

  • Read some bibliographical references related to the subject of work.
  • Start by seeing outputs of a simulation performed by the ORCHIDEE model as part of NMIP (Tian et al., 2018a, b).
    • look at the variable NH3_EMISSION which gives the emissions per m2 of each type of vegetation. It is an information to combine with the file VEGET_MAX which gives us the fraction of mesh occupied by each type of vegetation.
  • See the outputs of the NH3 simulations made by INCA to compare them with those of ORCHIDEE.

Team meeting: 13/03/2019

Evaluate the outputs of the NH3 (monthly, seasonal (averaged, maximum, minimum)) simulations of ORCHIDEE (2016) and INCA.

Note: In this section the maps of the NH3 emissions simulated by the ORCHIDEE model are not corrected by the CONTFRAC.

What is the temporal variability of the emissions of NH3 mainly for the months of May and September?

Recommendations

  • include the global balances of the emissions of NH3 for ORCHIDEE and INCA for the period of 2000-2014.

Team meeting: 20/03/2019

Global balances of the emissions of NH3 for ORCHIDEE (black) and INCA (red) for the period of 2000-2014.

What is the origin of this difference between the global balances of the emissions of NH3.

Recommendations

  • Focus on NH3 emissions from the agricultural sector for INCA.
  • See references and inventories.
  • Compare the emissions of NH3 for INCA with those of the EDGAR inventory.
